Under Jim O’Neil, the 49ers have one of the worst defenses in NFL history

When you think about what the San Francisco 49ers are currently doing on the defensive side of the ball, it's all kind of amazing. Now it's not amazing in any way that's good, or productive, or promising, that's not it at all. It's amazing in the sense that it's quite possibly one of the more horrific performances we've ever seen. Make no mistake people, the Niners have one of the worst defenses of all-time.

Don't believe me? Well, let's look at some numbers and facts. The 49ers have given up 260 points in eight games this season, and that's with a shutout in Week 1. That would mean the team is on pace to give up 520 points overall, which averages out to 32.5 per game. If you look at their last seven games, the total actually goes up to 37 points per contest. So if things stay status quo, San Francisco will probably allow something closer to 550 points this season.

Looking deeper into the overall horribleness, the 49ers are currently on pace to give up 3,088 yards rushing, which would be the most in the NFL since the 1978 Buffalo Bills. They've given up 240 yards or more on the ground in three straight games, which no team has done since the 1977 Kansas City Chiefs. Also, per Elias Sports, they are the only team to allow a 100-yard rusher in seven straight games.

San Francisco has done all of this despite drafting heavily on defense the past four years. Since 2013, general manager Trent Baalke has used 10 of a possible 15 picks in rounds 1-3 on defensive players. If you break those selections down, he's taken three defensive linemen (Tank Carradine, Arik Armstead, DeForest Buckner), three linebackers (Corey Lemonier, Chris Borland, Eli Harold), two cornerbacks (Jimmie Ward, Will Redmond), and two safeties (Eric Reid, Jaquiski Tartt). It's a pretty balanced approach in terms of positions, and eight of those players are still on the roster (Lemonier and Borland being the exceptions). When you look at guys like Buckner, Armstead, Ward, and Tartt, and add in other young talents like Aaron Lynch and Rashard Robinson, it almost looks like the Niners have some nice building blocks on paper.

So what's the problem? Well, there is that whole issue of coaching, and believe me, the employment of defensive coordinator Jim O'Neil is a cause for concern. The hire was a curious one, to begin with, as O'Neil's two years in the same position with the Cleveland Browns weren't anything to write home about. In 2014, the Brown's secondary played well enough, but the run defense was last in the league with 2,265 yards allowed. The following season, head coach Mike Pettine stepped away from his role with the defense and gave the reigns totally to O'Neil. The results were disastrous as the Browns quickly descended towards the bottom of the NFL in most major defensive categories including points allowed, total yards allowed, and yards per play. The issues with the run defense also remained, as the Browns finished 29th, once again allowing over 2,000 yards (2,055). Also notable under O'Neil was the lack of development from younger players, something that's held true in San Francisco.

Most of these issues seem to be directly related to O'Neil's scheme, which one source called "a guessing game" during his time in Cleveland.

Rather than being assigned specific gaps, Cleveland's defensive linemen play different techniques based on how their offensive counterparts are blocking them. The linebackers, then, are expected to guess what technique their teammates are using, scrape through the resulting mess and make the play. Opposing offenses have identified this flaw on film and are repeatedly, week-after-week, gashing the edge of Cleveland's defense. It's a completely chaotic approach to stopping the run, and players have said—off the record—they're spending way too much time thinking, and not nearly enough time reacting.

This is basically an issue with gap integrity, something O'Neil has admitted he's not familiar with. When asked in a press conference how he would assess the gap integrity along his defensive line, O'Neil's response was, "I don't know what you mean by that." Meanwhile, the defense has been destroyed on the ground week after week with no end in sight.

Despite the issues at hand, head coach Chip Kelly has repeatedly said that he's not making any changes to his defensive staff. While it's understandable that Kelly wants to stay loyal to his coaches, continuing to employ O'Neil at this point is bordering on insanity. The maligned coordinator's confusing scheme isn't doing San Francisco's young defensive building blocks any favors, and at this point, you'd have to wonder if it's stunted their development.

What's most maddening is that even if the team relieved O'Neil of his duties now, there isn't really anyone else on the staff you could see as a long-term answer. Senior Defensive Assistant Jason Tarver has experience as a coordinator, but his time running the show in Oakland with the Raiders from 2012-2014 was a disaster. His units never finished better than 29th overall in total defense. Combine that with the fact that many defensive coaches steer clear from Kelly because of his fast-paced scheme, and the answer isn't clear right now. Still, even if the 49ers had to finish out the year with Tarver and get creative in the offseason (if Kelly's still around) it's better than the alternative. O'Neil has to go, and he has to go now.

    Worst defense in history? More proof that this organization has no clue. I'm embarrassed to be a Niner Fan.

    Thanks Al, Losing Bo, Ray Ray and DT Williams, three starters, would cripple any defense. The blame is on the GM, how could he start a season without a nose tackle and legitimate inside linebackers to fill in when the starters went down. Add in your points on a D- coordinator that seems not to have a clue and BOOM.

    Niner, Webzone said we could have $100M in cap space. And we will probably sign nothing but torn ACL guys because no one else wants to play here.

    Who cares? Are we still leading the league in being under the cap?

    We're already paying Tomsula, I wish we could get him to come back coach up that D-line...

    I , unfortunately, have to agree with you. I had hopes that the new DC would simplify the scheme and develop the talent that we have accumulated. I always thought that Mangini's schemes were too complex. However, just watch a typical play and it's obvious that the DL has no idea of what they're doing. Hell yes, fire him now. What do we have to lose? The chase to be the all-time worst NFL defense?

    The whole coaching staff should be dismissed at the end of the season. You might be better off giving O'Neil his walking papers now, but who takes his place? I thought ManGenius was OK last year, certainly better than this mess. And truthfully, Kelly hasn't been that impressive either. The problem is, what quality coach would want to work for this dysfunctional team? I think the ineptitude continues until York hires his version of John McVay and Bill Walsh, or sells the team to someone with the intelligence to hire good people and get the hell out of the way.

    Mike Nolan was available and even semi-volunteered for an interview. Just saying.

    The play with three defensive holdings was actually creative. Other than that it was so bad. Why did we pick to super tall (can't get low) defensive lineman from Oregon? Oregon isn't known for great defense. They get no pressure on a QB without a full on blitz. I had a bad feeling when I heard the defensive coordinator from Cleveland was coming here.

We're just four days away from finding out what the San Francisco 49ers do with their collection of 2021 NFL Draft picks. If past history is any indication, the 49ers will make some moves along the way that result in some shuffling of their current list of nine picks, but right now the 49ers own one pick in each of the first four rounds, three in Round 5, and one in both Round 6 and Round 7. With the clock winding down before the draft gets underway Thursday night (8 p.m. ET/5 p.m. PT), let's take a look back at what's happened over the past ten years at each of the draft slots the 49ers currently own. The results are mixed, but there's also been plenty of talent to come out of those spots. Pick 3 (Round 1) Last 10 picks at this

The San Francisco 49ers announced that the team has re-signed offensive lineman Tom Compton to a one-year deal. Washington made Compton a sixth-round selection out of South Dakota in 2012. The offensive lineman has 106 game appearances through his nine NFL seasons. Compton, 31, has spent time with Washington (2012-15), the Atlanta Falcons (2016), Chicago Bears (2017), Minnesota Vikings (2018), New York Jets (2019), and 49ers (2020). He has appeared in seven games with three starts with San



Kyle Shanahan was the one who called about Aaron Rodgers as 49ers did their due diligence

By David Bonilla
May 3, 2021

San Francisco 49ers head coach Kyle Shanahan joined the Rich Eisen Show on Monday morning and discussed the team's interest in Green Bay Packers quarterback Aaron Rodgers leading to the draft. Really, it was just the team doing its due diligence, but it was a hot rumor that made for some interesting discussion leading to the draft. "The exact truth is I didn't want to wake up the next day, on Friday, and see Aaron Rodgers, one of the best quarterbacks in this league, traded, without doing any due diligence on it," Shanahan explained to Eisen (h/t to Cam Inman of Bay Area News Group). "So I just called Matt and asked him if there was anything to it, and Matt told me I'd be wasting my



Schefter: Compelling QB options have 49ers going back and forth on draft decision

By David Bonilla
Apr 27, 2021

Kyle Shanahan and John Lynch have the biggest decision of their San Francisco 49ers tenure approaching. On Thursday night, the head coach and general manager duo will select a quarterback of the future with the No. 3 overall pick, a selection for which they traded a haul of draft picks, including first-rounders in 2022 and 2023. If they hit on the pick, it could lead to consistent success for the foreseeable future. If they miss on the pick, though, it could put one or even both of them on the hot seat within the next few years. For most of the time since that March 26 trade, the betting favorite has been Mac Jones of Alabama. Adam Schefter of ESPN believes the Crimson Tide product would have been the selection had the draft taken place a month ago. However, a
